'To allwhomz'tmag concern:

Be it known that we, PAUL BERNARD and MAXIME BARBE', both citizens of theRepub- "lie of France, and residing, respectively, at

Boulogne-sur-Seine and Paris, France, have invented anew and useful Improvement in which improvements are fully set forth in the'following specification;

This invention relates to an apparatus for lighting and extinguishing gas burners of street lamps of the kind operated by pres pressure waves in the piping system. i

burner with a pilot light for producing the lighting'and it can be used for inverted V 'lburners."'By means of the apparatuslall" the evening, some of them extinguished for the'burners of a system can be lighted in reasons of economy in the middle ofthe "night, and the rest of the burners QXlZlH' guished at day break." This apparatus is therefore a'three-stroke apparatus.

A construction of the apparatus isillus trated by wayoit' example'inthe accompanying drawings. In'the said drawings,

Figure 2is a vertical section of the same apparatus, the bellbeingin its raised p'osi Figs. 3,4, 5 and 6 are'diagrammatic sec tional vlews showing the difi'erent positions assumed'by the parts during operation.

"Figs. 7,8, 9, 10,11 and l2 arediagra'mmatic sectional views of aslightlyinodified form of the invention, and likewise show the different positions assumed by the parts durin operation. H ig. 13 is a diagrammatic sectional view showing a controlling part for a two-stroke system.

' Fig. 14 is a diagrammatic sectional View of a further modified form of apparatus in which glycerine is used.

Figure 15 is an enlarged fragmental' detail of Figure 1.

The apparatus comprises a cup A ure 1) containing mercury or other liquid,

mercury being preferable as it makes it posparatus, but it is obvious that any other sible to reduce the dimensions of the apwith'the pressure of each burner.

in pressure can be slow or quick. 1

liquid of a lower density could be utilized.

a tube C extendingto the burner or burners controlled by the apparatus;

A bell D' under which is (secured a tube E, d1ps into the cup A, andround-the said "bell Dare'arranged six ribs F, three ofwhich are arranged at the top, and three atthe bottom. 'Theseribs F guide the bell D in the cup Aand prevent the walls of the bell from adherin to those of the cup A. "Theapparatus accordingto the present inventlon is intended to'bepla'ced on each" Controlling parts 1 (Figure1),(5r (Figure 7),Gi (Figure 18), each of which is provided with internal groovesand stop notchesorprojections, are secured-at the top of the bell D. These parts are interhangeable, according to the kinder fi ht. ing to be obtained. i I o t h A rod H (Figure 1) passing right through the upper part of the cup A, forms an axis L which engageswith the grooves of oneof the-partsG orGr 01 G. i

The working of the apparatus is brought about by waves of pressure in the gas supply, tlratis, by rises in gaspressure followed by returnto normal pressure. The bell D. is provided'with ballast in order that it may be kept from rising except under the action of the deslred pressure wave, in' accordance The rise 'The working of the apparatus will vary as will be explained, inaccordance with the shape of the controlling part G G or G used. Each of the said cases will beexamined in succession: i i

1. Working of the apparatus with the partG i w Let it be assumed that the apparatus is in the position shown in Figure 1, the bent point L of the rod L engaging at awith the part G First stroke: The pressure waveis sent into the piping. The bell D will rise (Figure 2). The tube E secured under the bell D, will emer e from the mercury and afford passage to the gas through the tube C so that it can pass to the burner where it is lighted bymeans of the pilot light, not shown in the drawing. During the rising, the bell Dhaving lifted the weight K, the latter will no longeract on the beam I. The .bent point of the rod L will be pushed from left to right by the weight J which sinks, and the said point follows the left hand groove and, reaches the point Z) (Figure 2) which will lim'itthe lift ofthe bell D. When the pressure is reduced to normal, the bell D- willsink again, but the red L pushed by the weight J will limit the descent of the bell D by engaging at c (Figure 3). The tube E will not descend again sufficiently to dip into themercury, and the burner will remain alight.

Second stroke The pressure wave is sent .into the piping. As shown in Figure 4:, the rod point L will-engage at d. The pressure having been brought back to normal (Figure5), the rod point engages the bell Diat 25. e. The position of the tube E will obviously be similar to during the first stroke, and

the burner remains alight.

Th rd stroke :The pressure wave is sent into the piping (Figure 6). The rod point L engages at f. The pressure having been brought back to normal, the rod L follows the, right hand groove so that it engages the bell D at a (Figure 1) and the bell can now descend t0 the position preceding the first stroke. The tube It closes the passage of the 7 gas by dipping into the mercury and the .burner, isqextinguished. The bell, D in its .idescent, has. released the weight K j which acts again on the'beam I.

40 It should be noted that durin the rising,

the weight J will push the rod L from left I to right in the bottom portion of, anyone of theparts G G G .used: In its descent, the weight Kv will .push the rod L from right to left in the upper portion of the same part.

.A movement of the bentpoint of the rod L is ,thereforezalways ensured, whatever be the part G G or G? used.

7 G 2. l/Vorking ofthe apparatus with the part First stroke :-The bell D j and the mercury having the same position as in Figure 1,-; and, the bent point of the rod L engaging atthe point 9 (Figure 7), thepressure wave is sent into the piping. The-rod L following ,theleft hand groove,swill engage at h (Fig two stroke one.

lows the right hand groove and its point L engages the bell D at k. Owing. to the descent of the bell D, the tube E is caused to dip into the. .mercuryand the burner is-.iextinguished.

Third stroke :The pressure wave is sent into the piping. The rod point L (Figure 12) arrives at Z, but the tube E does not emerge from the mercury and the burner remains extinguished. The normal pressure is reestablished: The rod point L returns to g, the position preceding the first stroke (Figure 7 8. lNoiking of part G V The working will be the same as with the part G except that the second stroke will be done away with. This apparatus is a 'It is intended for cases which require only a single lighting and a single extinction.

As already stated in the foregoing, all these apparatus can work with liquids other than mercury, for instance withglycerine. But asshow'n in Figure 14, in the event of glycerine being used, a small cupN containing mercury, is arranged at the top of' the tube C The tube E will therefore close and ?en the passage for the gas into the cup l the-glycerine being utilized merely for 95 the joint or seal between the bell and the lar e cup.

Flaving now particularly described and ascertained thenature of our said invention and in what manner the same is to be performed, vwe declare that what we claim is l. Inan automatic gas controller, the combination of a rising and falling, pressure operated gas bell; a controlling member mounted on the top of the bell to move therethe apparatus with the withand provided with grooves and pro jections, a weighted balance beam disposed 7 above and extending horizontally across said member; and a rod depending from and rigidly related to the central portion of said. beamiand having apart arranged to cooperate with said grooves ;and projections llO . to control. the movements of the bell.

2. In an automatic gas controller, the combination of risingand falling, pressure-operated gas bell; a controlling member mounted on the top of the bell to move therewith and providedwith grooves and ,projections within its interior; a weighted balance beam disposed above the controlling member; and a rod rigidly related to said beam and having a part which projects into the interior of said controlling member and which is bent at its free end for cooperation with the grooves and projections to control the movements of the bell.

3. An automatic {gas .controller, comprising, in. combination,,a rislng and falling, pressure-operated gas bell; a controlling member mounted on the top of the bell to move therewith; a rockin balance beam disposed above and extending horizontally across the controlling member; and a rod depending from and rigidly related to said beam for cooperation with said member to control the movements of the bell.

4. An automatic gas controller, comprising, in combination, a rising and falling, pressure-operated gas bell; a controlling member mounted on the top of the bell to move therewith; a rocking balance beam disposed above the controlling member and having a weight at each end, one weight being fixed and the other movable relatively to said beam; and a rod rigidly related to said beam for cooperation with said member to control the movements of the bell.

5. An automatic gas controller, as claimed in claim 4, in which the movable weight is suspended by a link from the beam and is adapted to rest on the top of the bell during the rising movement of the latter.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
